Not fluoridated

Fluoride

Not added

CDC's My Water's Fluoride listing does not report this system as fluoridating its drinking water.

Per CDC My Water's Fluoride · See details below

Past 5 years: 44 health-based violations on file, all marked Resolved or Archived. See compliance history below.

Risk classification follows EPA's published values for safe drinking water, with caution and concern bands reviewed by a clinician. Past resolved violations do not influence this card. See methodology.

Lead service line inventory

No inventory data on file

We do not yet have this utility's published Lead Service Line Inventory on file. The EPA Lead and Copper Rule Improvements (LCRI) required every community water system to publish one by October 16, 2024 and to identify and replace any lead lines within 10 years. How lead enters drinking water.

Phase 1 coverage focuses on the largest NC utilities. Smaller systems will be added; in the meantime, ask your utility for their inventory or check their Consumer Confidence Report.

Lead and copper test results

The most recent measurement per contaminant from EPA's Lead and Copper Rule sampling.

Why only lead and copper, and not arsenic, nitrate, or others?

EPA's bulk SDWIS download is the only nationwide per-system sample data they publish, and it only includes the Lead and Copper Rule table. Values for other regulated contaminants (TTHMs, nitrate, arsenic, etc.) appear on this page only when they trigger a violation. For the full per-system contaminant suite, see the utility's annual Consumer Confidence Report (link further down the page).

Most recent measurements per contaminant (Lead and Copper Rule) . Sorted by risk: concern first, then caution, then unrated, then safe.
Contaminant	Most recent	Date	Risk
Lead PB90	0 mg/L	December 31, 2023	Below regulatory thresholds Lead has no safe level (MCLG=0). LCR action level is 0.015 mg/L for the 90th-percentile sample; the LCRI (Oct 2024) lowers the action level to 0.010 mg/L effective Nov 2027. Caution at any detection above LOD; concern anchored to the future LCRI value (0.010 mg/L) for forward consistency. Learn more about Lead. Source.

Fluoride

Per CDC My Water's Fluoride

CITY OF RIO HONDO does not add fluoride to its drinking water.

This system has not reported adding fluoride to its water on CDC's My Water's Fluoride listing. Natural fluoride may still be present at trace levels from the source water; the utility's annual water quality report has the latest measured concentration.

Compliance history

EPA-recorded violations against this system over the last 5 years.

How to read this section

Health-based violations are when a measured limit was exceeded; the measured concentration is shown alongside the EPA federal limit where SDWIS published it. Monitoring and reporting items are paperwork issues (missed sample dates, late filings) that do not themselves indicate unsafe water.

3 active health-based violations

EPA records 3 health-based violations that have not yet been resolved. An additional 44 health-based violations in the last 5 years are already resolved.

Data from EPA SDWIS (violation records) , last refreshed May 24, 2026.

Where to see every contaminant this utility tested for

EPA's bulk SDWIS dataset gives MyTapWater.us per-system measured values for lead and copper, plus violation records for everything else. To see every regulated contaminant this utility tested for in the past year (TTHMs, HAA5, nitrate, arsenic, fluoride, chromium, etc.) with measured values, read the utility's Consumer Confidence Report (CCR).

Every community water system is required by EPA to publish a CCR annually, by July 1, listing every contaminant they sampled, the measured value, the federal limit, and any health-based exceedances. Most utilities post the report online; some mail it with your bill.

How to find CITY OF RIO HONDO's CCR:

Search the web for "CITY OF RIO HONDO consumer confidence report" . The PDF is usually on the utility's own website.
Or call the utility directly. Their phone number is in the contact section below.
